Command: eval delete

The eval delete command is used to delete evaluations. It should be used cautiously and only in outage situations where there is a large backlog of evaluations not being processed. During most normal and outage scenarios, Nomad's reconciliation and state management will handle evaluations as needed.

The eval broker is expected to be paused prior to running this command and un-paused after. These actions can be performed by the operator scheduler get-config and operator scheduler set-config commands respectively.

Usage

nomad eval delete [options] [args]

It takes an optional argument which is the ID of the evaluation to delete. If the evaluation ID is omitted, this command will use the filter flag to identify and delete a set of evaluations.

When ACLs are enabled, this command requires a management token.

General Options

• -address=<addr>: The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Defaults to http://127.0.0.1:4646.

• -region=<region>: The region of the Nomad server to forward commands to. Overrides the NOMAD_REGION environment variable if set. Defaults to the Agent's local region.

• -namespace=<namespace>: The target namespace for queries and actions bound to a namespace. Overrides the NOMAD_NAMESPACE environment variable if set. If set to '*', subcommands which support this functionality query all namespaces authorized to user. Defaults to the "default" namespace.

• -no-color: Disables colored command output. Alternatively, NOMAD_CLI_NO_COLOR may be set. This option takes precedence over -force-color.

• -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively, NOMAD_CLI_FORCE_COLOR may be set. This option has no effect if -no-color is also used.

• -ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the NOMAD_CACERT environment variable if set.

• -ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both -ca-cert and -ca-path are specified, -ca-cert is used. Overrides the NOMAD_CAPATH environment variable if set.

• -client-cert=<path>: Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify -client-key. Overrides the NOMAD_CLIENT_CERT environment variable if set.

• -client-key=<path>: Path to an unencrypted PEM encoded private key matching the client certificate from -client-cert. Overrides the NOMAD_CLIENT_KEY environment variable if set.

• -tls-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the NOMAD_TLS_SERVER_NAME environment variable if set.

• -tls-skip-verify: Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if NOMAD_SKIP_VERIFY is set.

• -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the NOMAD_TOKEN environment variable if set.

Delete Options

• -filter: Specifies an expression used to filter evaluations by for deletion. When using this flag, it is advisable to ensure the syntax is correct using the eval list command first. Note that deleting evals by filter is imprecise: for sets of evals larger than a single raft log batch, evals can be inserted behind the cursor and therefore be missed.

• -yes: Bypass the confirmation prompt if an evaluation ID was not provided.

Examples

Delete an evaluation using its ID:

$ nomad eval delete 9ecffbba-73be-d909-5d7e-ac2694c10e0c
Successfully deleted 1 evaluation

Delete all evaluations with status pending for the example job:

$ nomad eval delete -filter='Status == "pending" and JobID == "example"'
Are you sure you want to delete 3 evals? [y/N] y

Successfully deleted 3 evaluations

Delete all evaluations for the system and service whilst skipping all prompts:

$ nomad eval delete -filter='Scheduler == "system" or Scheduler == "service"' -yes
Successfully deleted 23 evaluations
